Product details
Overview
ESD1LIN24DYFRQ1 from Texas Instruments is a single-channel, bidirectional automotive-grade TVS diode for LIN bus ESD protection. It features ±24V working voltage, 2.3pF typical I/O capacitance, 37V clamping voltage at 4.3A (8/20µs), AEC-Q101 qualification, and operates from –55°C to +150°C - deployed in headlight modules, door ECUs, and climate control units.
For engineers reviewing the ESD1LIN24DYFRQ1 datasheet, ESD1LIN24DYFRQ1 pinout, ESD1LIN24DYFRQ1 application, or ESD1LIN24DYFRQ1 equivalent, this page delivers verified electrical specs, SOD-323 (DYF) package details, LIN-specific clamping performance, thermal resistance data, and validated automotive alternative options - all aligned to TI's SLVSGS4D production datasheet (Rev D, Oct 2025).
Technical Context
The ESD1LIN24DYFRQ1 functions as a passive bidirectional clamp between LIN signal line and ground, activating only during transients exceeding ±25.5V breakdown voltage. Its low dynamic resistance (0.5Ω) ensures minimal voltage overshoot during IEC 61000-4-2 ±30kV contact discharge events.
It supports LIN data rates up to 10Mbps due to 2.3pF line capacitance and maintains ultra-low leakage (<50nA at ±24V), enabling robust operation under battery-reverse and jump-start conditions while preserving signal integrity in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | ±24V - withstands automotive short-to-battery events without conduction. |
| Clamping Voltage (VCLAMP) | 37V at 4.3A (8/20µs) - limits transient stress on downstream LIN transceiver inputs. |
| I/O Capacitance (CL) | 2.3pF (typ) - enables clean signal integrity up to 10Mbps LIN data rate. |
| ESD Rating (IEC 61000-4-2) | ±30kV contact / ±30kV air-gap - exceeds Level 4 immunity for automotive ECU interfaces. |
| Dynamic Resistance (RDYN) | 0.5Ω - minimizes voltage drop across diode during clamping, reducing protected IC stress. |
| Leakage Current (ILEAK) | ≤50nA at ±24V - negligible power loss in always-on LIN nodes. |
| Operating Temperature | –55°C to +150°C - qualified for under-hood and cabin ECU placement per AEC-Q101. |
Pinout & Package
SOD-323 (DYF) package: 1.70mm × 1.30mm body, 0.45mm max height, leaded for AOI compatibility, MSL Level-1 (260°C, unlimited reflow).
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD751DYARQ1 | Lower capacitance (1.6pF), lower surge rating (2.8A), SOD-523 (DYA) package (1.60mm × 0.80mm). | Better suited for space-constrained LIN nodes requiring higher data-rate margin or tighter layout density. | Select when board real estate is limited and 10Mbps margin must be preserved with lower parasitic loading. |
| ESD761DPYRQ1 | Lowest capacitance (1.1pF), smallest X1SON (DPY) footprint (1.00mm × 0.60mm), MSL Level-1, but same 36.3V clamping at 1.8A. | Optimized for ultra-dense automotive modules (e.g., LED driver ICs) where size and signal fidelity outweigh surge robustness. | Choose for next-gen compact ECUs where 1.1pF capacitance enables future LIN-FD migration paths. |
Compared with ESD751DYARQ1 and ESD761DPYRQ1, the ESD1LIN24DYFRQ1 delivers highest surge robustness (4.3A) and largest thermal margin (RθJA = 705.4°C/W) in the family - making it optimal for high-temperature under-hood locations where sustained clamping energy dissipation matters most.

FAQ
What is the maximum clamping voltage of ESD1LIN24DYFRQ1 during an IEC 61000-4-5 surge event?
The ESD1LIN24DYFRQ1 clamps to 37V at 4.3A (8/20µs waveform), per TI's SLVSGS4D datasheet Section 5.7. This value reflects worst-case transient suppression at rated surge current - critical for ensuring downstream LIN transceivers remain within absolute maximum ratings during load-dump or coupling events. The device maintains this clamping performance across its full –55°C to +150°C operating range.
Does ESD1LIN24DYFRQ1 support bidirectional signal protection on LIN bus lines?
Yes, ESD1LIN24DYFRQ1 is explicitly designed as a bidirectional ESD suppressor. Its symmetrical breakdown voltage (±25.5V min) and matched clamping behavior (37V positive/negative) ensure protection regardless of LIN signal polarity or battery reverse connection - a key requirement for automotive LIN networks where wiring faults or jump-start errors may occur.
What package type and dimensions does ESD1LIN24DYFRQ1 use?
ESD1LIN24DYFRQ1 uses the SOD-323 (DYF) package: 1.70mm × 1.30mm body size, 0.45mm maximum height, with two gull-wing leads. It is MSL Level-1 rated (260°C, unlimited reflow), lead-free (Sn finish), and optimized for automatic optical inspection (AOI) in high-volume automotive PCB assembly.
How does ESD1LIN24DYFRQ1 differ from ESD751DYARQ1 in terms of ESD protection capability?
ESD1LIN24DYFRQ1 offers higher IEC 61000-4-2 contact discharge rating (±30kV vs. ±22kV for ESD751DYARQ1) and greater surge current handling (4.3A vs. 2.8A at 8/20µs). It also features higher I/O capacitance (2.3pF vs. 1.6pF), making it less suitable for ultra-high-speed LIN-FD but more robust for legacy LIN in thermally demanding under-hood locations.
Is ESD1LIN24DYFRQ1 qualified for automotive applications per AEC-Q101?
Yes, ESD1LIN24DYFRQ1 is AEC-Q101 qualified and rated for –55°C to +150°C operation. Its qualification covers HBM (±2500V), CDM (±1000V), and full automotive environmental stress testing - confirming suitability for safety-critical automotive ECUs including lighting, door modules, and HVAC systems per ISO 26262 requirements.
